Brent Key said the changes were needed to help Georgia Tech finish the season with three games left after a 44-17 loss to Louisville.
On Monday, Georgia Tech head coach Brent Key fired four assistant coaches, including defensive coordinator Jason Semore, Kyle Pope, Allen Mogridge, and Jafar Williams, two days after a 44-17 loss to the Louisville Cardinals.
The Yellow Jackets have lost four straight games, falling to 2-7 overall, while the defense ranks second-to-last in the Atlantic Coast Conference, allowing 418.9 yards per game.
Assistant wide receivers coach DeAndre Hopkins, a former NFL All-Pro with five Pro Bowl appearances, will serve as the primary receivers coach for the remainder of the 2026 season.
"These decisions are not ones that I take lightly, especially in-season," Key said, announcing new assignments including defensive backs coach Vinnie Sunseri taking over defensive play-calling duties.
Georgia Tech faces the Clemson Tigers this Saturday, followed by games against Wake Forest and Georgia, as the program attempts to finish the 2026 season.
